摘　　要：文中通过蒙特卡洛仿真,研究了CDMA20001x和CDMA20001xEV-DO系统在不同频率配置、不同组网方式下共存的系统容量损失情况。仿真结果表明,共存系统容量随着两个系统的频率间隔的增加而减小,随着组网方式的改变而改变,相同条件下1:1的共站组网方式时系统容量的损失最小。此外,根据仿真分析的结果,给出了减少系统间干扰的措施。This paper, by the Monte-Carlo simulation method, principally analyzes the network performance due to the co-existence of CDMA2000 1x and CDMA2000 1xEV DO under the different frequencies disposions and sites distributions. The simulation result shows that the capacity loss of the co-existent systems increases while the space of the frequencies decreases. Also the capacity loss changes while the site distribution changes. The capacity loss is minimum when the site distribution is 1：1. Finally several methods for reducing the interference impact on the performance are given.
